EWG dosn't work anymore ?

[punisher 5]

Hello, I bought your plugin last year to make a YT serie called RushToTheBeacon with french's youtubers. But today I was preparing for the next season of the event and the plugin does not work anymore ! I got an error in the log ! It was in 1.12, I update the plugin and my server in 1.12.2 but the error persists !

This is a pastebin link with the error found in the log: https://pastebin.com/2JBTiC8e

Make sure to run it on Spigot and not Craftbukkit.

I solved the problem ! It was Java 9 !
